Klondike - 16 chip ASIC Open Source Board - Preliminary

[Vl4dim1r]

Vl4dim1r,

http://projectklondike.org/big-troubleshoot should provide you TONS of GREAT troubleshooting ideas.  Cheers.

H@shKraker

Thank you very much for that. I've been to the project klondike site before, I guess I missed the troubleshooting section at the time. I'm going to look around at work tonight and see if I can find an o-scope.


EDIT: Nevermind on that oscilloscope, apparently I'm not "qualified" to operate it because I am just a lowly wrench turner. But I found a Tektronix 2213 60MHz locally for $100!
EDIT2: so after some poking around with a multimeter following the big troubleshoot guide, I'm getting about 10.5v from the power supply through the second can capacitor, and nothing from the 1.2v or 3.3v on either bank.

Not sure what I would do with a bare PCB - I'm skilled at hand soldering but have never tried SMT... I suppose I should learn (on a cheaper project).
I'm hoping once these 2nd gens test well I can put in an order to have them made like the liquidsynergy one I've acquired.

IrishFBall32,

You could TRY to hand solder the board (which would be a TRUE PITA) *OR* you could whip yourself up a DIY arduino reflow oven made from a converted convection toaster oven -> http://www.adafruit.com/blog/2011/07/22/reflow-oven-controller-shield/ .  These things are da *B-O-M-B* for small batch SMT work and they're fairly inexpensive:-D

If you have a Goodwill Outlet warehouse nearby, i recommend going there. I see low wattage toaster ovens all the time, but the day I went looking for my "reflow oven", I found a 1500W GE , retails about $250, for $3.

EDIT: Question, does anyone have a hot air reflow pen they're willing to sell? I'm having difficulty finding one for btc.

Vl4dim1r,

I once got krunk with an oscillator and a standard, bought from the hardware store heat gun.  Be careful though, don't drop that heat gun on your junk after it's been on for any time

H@shKraker

Unfortunately, I've checked all the local hardware stores and cant find a heat gun. Checked all the craft stores for embossing pens too, with no luck. Maybe they were just hiding somewhere...

EDIT: H@shKraker: Are you in the US? If so, was it one of the main chain hardware stores you found yours? What would I most likely find it with?

You can get it pretty cheap on Ebay i just bought one for 127$ 4in1 Search for hot air reflow station

Vl4dim1r,

This is the heat gun one should never drop on their junk after using it for any time -> http://www.lowes.com/pd_20960-97-0503040_0__?productId=1059297&Ntt=heat+gun&pl=1&currentURL=%3FNtt%3Dheat%2Bgun&facetInfo= ..... or QualitySeeds Ebay idea will also do the trick.

Zipiju,

Has the PCB run been fully funded?  If so how are things coming?  Hope all is well with you.

Yep, but I haven't ordered the PCBs yet (because the BTC price plummeted recently).
I'm going to order them in a couple of days (one or two) from iteadstudio.com. They should be here in 10 working days.
I still want the design tested before the december the 24th.
Other components from Mouser should be here this week (hopefully). They are already on their way.

Zipiju,
Does the Klondike driver need to be modified to accept the higher frequencies for example (--Klondike-options 1500)
just wondering about firmware and driver changes to support the new chips.

Yes, they both will have to be modified.
In the firmware, just a small mod to the config that is send to the chips.
In the driver, probably just the stuff around the clock frequency.

My local lowe's didn't have that specific gun, just the single temp Wagner, But they had a Porter Cable heatgun, same price, same wattage, variable speed, variable temp. I guess I will let it heat up and point it at a thermometer so I can mark on the dial where the necessary temps are. I actually used it to defrost my windshield last night xD

[h@shKraker]

Vl4dim1r,

Remember  ...... don't drop it on your junk if it's on or is still HOT

Yes, that is common sense. But I'll keep a barrier of sorts on my lap while I'm reworking, just to be safe

[h@shKraker]

zipiju,

Have you ordered your PCB for testing yet?  On the US side of the pond I've already submitted and gotten back full assembly production quotes from a board house I've used many times in the past.  Once you get the testing done successfully I'll be ready to do a  full reel run and show off some drop dead sexy Klondike16-55n pr0n :-D

Hey Zipiju,

I would like to personally thank you for carrying on with the gen 2 Klondike and for helping out with the Gen1 Klondike firmware.

Sent you 0.1 btc

Also, Klondike Gen 2 still uses 16 ASICs?

Do you need more Gen2 Avalon Asics? Kuz there is a guy here on the forums https://bitcointalk.org/index.php?topic=355616.0

selling some. Is that a good price? Do you need more chips? I could order some for myself and send some to you if you need them to do a full test run.

I would like to support the Gen2 effort.

[fasmax]

Does anyone here know what frequency the Avalon gen2 parts run at?
Is the hash rate close to the hash frequency or is the hash rate higher than the hash frequency because of the multiple cores?
Seems like with gen1 parts the hash rate was close to hash frequency.

[h@shKraker]

I do know the freq off hand BUT I'd bet it's the same freq as the Avalon Gen2 140Ghash boxes that show up from time to time at avalon-asics.  That's where I'm startign my testing when i do my board run.

Yes, they are already ordered. Should be here within two weeks.
